GRIN (Grow your Recycling Incentives Now) is the first on-line recycling rewards programme in Singapore. It is initiated by Veolia Environmental Services Singapore and supported by the National Environment Agency (NEA).

GRIN programme makes use of technology to accurately identify individual household or a community zone, weigh and record the amount of recyclables collected. Upon online registration at www.grin.com.sg, every kg of recyclables collected will be converted to GRIN points at which they can either redeem for privileges or donate for a green cause.
